WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 794,470, dated July 11,1905.

.Application filed February l5, 1905. Serial No. 245,668.

To all whom it may concern:

Beit known that I, WILLIAM E. SHERwooD, of Oneida, in the county ofMadison, in the State of New York, have invented new and usefulImprovements in Window Screens, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention relates to the class of win- Io dow-screens whichcomprise two frames each provided with a sheet of wire-cloth and whichare joined slidably, thereby rendering them adjustable, so as to permitthe same to be placed in window-frames of different widths, and theinvention has special reference to the style of screens which have theirmembers formed from sheet metal.

The main object of the present invention is to produce a screen ofthecharacter referred to which shall possess great strength, rigidity, anddurability, and at the same time shall be inexpensive in its manufactureand also.

present a neat appearance.

To that end the invention consists in the novel construction andarrangement of the component parts of the screen, as hereinafter fullydescribed, and set forth in the claims.

In the accompanyingdrawings, Figure 1 is a front view of a window-screenembodying my invention. Eig. 2 is an enlarged vertical section taken onthe dotted line X X in Fig. 1. Fig. 3 is an enlarged longitudinalsection taken on the line Y Y in Fig. 1 viewed in the directionindicated by the arrow. Fig. 4f is an enlarged perspective View of acorner portion of the inner screen-frame, and Fig. 5

is a like view of a corner portion of the outer screen-frame.

Similar letters of reference indicate corresponding parts.

This screen comprises two frames A B, sliding one in the other, wherebyit can be lengthened or shortened horizontally to accommodate itself towindow frames of various widths, which frames are formed from sheetmetal of any suitable kind. The inner frame A is composed of top andbottom members c a and one side member at. Each of these frame membersconsists of a plate which is primarily folded longitudinally upon itselfto form two strips one strip of each member being inserted between themeeting member and abuts against the fold thereof.

D represents a sheet of the usual wire cloth ory netting, which has itstop, bottom, and one side margin inserted between said strips and alsoabutting against the said folds, through which overlapping strips passrivets Z d, which rigidly unite the frame members.

The said plates or members a ct a', with the inserted strips ofwire-cloth, are then bent longitudinally on lines parallel to theaforesaid folds, thereby producing lianges c e e, disposed at rightangles thereto. The forming of lflanges at the top and bottom causes thewire-cloth to be tightly stretched in one direction and securelyclenches the same to the frame members and Vat the same time addsstrength and rigidity to the frame. To the front of said inner frame Iapply a vertical stay A', which consists of a metal plate folded in themanner aforesaid to form two strips f f, one of which is insertedbetween the strips b of the top and bottom frame members A A andpreferably secured by means of rivets g g. The other side margin of thewire-cloth D is inserted between the latter strips and abuts against thefold. The plate or stay is then bent at right angles on a lineparallelto the line of fold to form a flange t, whereby the saidwire-cloth is securely clenched and tightly stretched in the otherdirection. The outer frame B is composed of top and bottom members c' c'and a side member c. Each of the said frame members vl vl consists of aplate that is primarily folded longitudinally upon itself at the centerof the width to form two strips jj' and thence bent at right angles on aline parallel to the fold to form a iiange lo. The side member rl islikewise folded and-bent to form two strips la' c and a flange Z.

the two strips of E represents the other sheet of wire cloth or netting,which has its margin inserted between the strips j Za and clenched inthe flanges 7c Z the same manner as the aforesaid wire-clothD. Thestrips j /r are lapped one onto the other and rigidly united by means ofrivets m m. The said flanges 7c /c of the top and bottom members arefurther bent to form longitudinal guards, as indicated at n n and moreclearly shown in Fig. 5 of the drawings. These guards engage the top andbottom flanges of the inner frame A and sustain Said frame laterally inthe outer frame.

By bending the Lipper and lower members of the outer frame, asaforesaid, they assume a U shape in cross-section, and the wire-cloth istightly stretched in one direction.

To the back of the outer frame is applied a vertical stay F, whichconsists of a metal plate, which is provided with a double fold in whichthe other margin of the wire-cloth E is clenched, and thereby stretchedin the other direction. The stay has its ends inserted between thestrips jj' and rigidly secured by rivets 0 0.

G represents an auxiliary vertical stay, which is disposed opposite thestay F and rigidly secured at its end to the guards in any suitablemanner, preferably by means of rivets a2 a2, between which stays the'frame A slides. This auxiliary stay is formed with aninwardly-projecting flange o', which is adapted to engage the flange /zof the stay A' on the inner frame when the frames are extended to limittheir movements.

I preferably form the auxiliary stay G of a plate folded and bentlongitudinally like the stay A. The said stays A G are designed to lieclose to the wire-cloth to effectually eX- clude flies, insects, zac.

What I claim is` l. A'win'dow-screen comprising two slidably-joinedmetallic frames, having their members composed of plates, each foldedlongitudinally at the center of its width to form two strips, one stripof each plate being inserted between the strips of the meeting plate andrigidly united, and a sheet of wire-cloth secured between the strips ofeach frame, as set forth.

2. A window-screen comprising two slidably-joined metallic frames havingtheir members composed of plates, each primarily folded longitudinallyat the center of its width to form two contiguous strips, one strip ofeach plate being inserted between the strips of the meeting plate andrigidly united, and each plate secondarily deflected at right angles ona line .parallel to the fold to form marginal flanges,

and the sheets of wire-cloth inserted with their marginal portionsbetween the strips of the respective members and clenched within thesaid flanges, as set forth.

3. A window-screen comprising two metallic frames sliding one in theother and each having a top, bottom and one side member,

each having a top, bottom and one side member, the inner frame havingits members formed L-shaped in cross-section, the' outer frame havingits side member likewise formed and its top and bottom members formed U-shaped in cross-section, and the sheets of wire cloth inserted into saidframes and clenched therein, as set forth.

5. A window-screen comprising two metallic frames sliding one in theother and each composed of a top, bottom and one side member, the innerframe having its members each composed of a plate folded longitudinallyat the center of its width to form two contiguous strips and one stripof each member inserted between the strips of the meeting member andrigidly fastened, the plates each deiiected on a line parallel to thefold to form a flange, the members of the outer frame, also composed ofplates likewise folded and deflected, the top and bottom fianges of saidouter frame terminating respectively with downwardly and upwardlydeflected guards engaging the lianges ofthe top and bottom flanges onthe inner frame, and the two sheets of wirecloth having their marginalportions inserted between the strips of the respective frames andclenched within the said flanges, as set forth.

6. A window-screen comprising two metallic frames sliding one in theother and having their members each composed of a plate foldedlongitudinally upon itself at the center of its width to form twostrips, a vertical stay. rigidly connected at its end to the top andbottom members of the inner frame,.a pair of vertical stays connected attheirends to the yhaving their ends inserted between the strips andrigidly secured thereto, as set forth.

8. Awindow-screen comprising two slidably-joined metallic frames havingtheir members rigidly united and each composed of a plate foldedlongitudinally upon itself at the center of its width to form twostrips, the

IOO

sheets of wire-cloth secured between said A strips, vertical stayssecured at their ends between the strips of the top and bottommemy n Abers of the frames, and arranged one in the path of the other to limitthe outward movement of the frames, as set forth.
